New Zealand seeks global support for tougher measures on online violence

New Zealand and France will today launch a campaign to end the promotion of extremist content online, exactly two months after the Christchurch Mosque attacks, in which 50 Muslims were murdered as they prayed.

New Zealand Prime Minister Jacinda Ardern and French President Emmanuel Macron will unveil the plan, dubbed "Christchurch Call" on the sidelines of a G7 meeting in Paris.

It'll urge nations to enforce laws banning extremist material and set new rules for media reporting on terrorism.
